LEASE-ROD-SUPPORTING DEVICE.

Specification of Letters- Patent.

Patented Sept. 24, 1907.

Application led September l0, 1906. Serial No. 334,007.

To all whom fit may concern:

Be it known that I, WILLIAM L. GILBERT, a citizen of the United States,residing at Auburn, in the county oi Androscoggin and State of Maine,have invented certain new and useful Improvements inLease-Rod-Supporting Devices, of which the following is a specification.

My present invention relates to improvements in looms and moreespecially to an improved device or attachment for supporting leaserods.

The object of the invention is to provide a device or apparatus by whichthe lea-se rods will be supported in of the warp have become so securelyattached to or entangled with each other as to be incapable of automaticseparation without breaking, the loom will be automatically stopped.

A further object is to provide an attachment to produce these resultswhich shall be simple, durable and eflicient in operation and which maybe manufactured at a minimum cost and be easily applied to any existingloom.

The invention is illustrated in the accompanying drawing in which-Figure l is a side elevation of a suicient portion of a loom toillustrate the application of my invention. Fig. 2 is a plan view of oneof the attachments showing a portion of the lease rods, and Fig. 3 is asection on line V3 3 of Fig. 2. Fig. 4 is a view of the opposite endattachment with an indicator attached.

Referring by reference characters to this drawing, the numeral 4designates the frame of the loom, 5 the harness, 6 the warp threads, and7 the rock lever oi the ordinary stop motion mechanism. These parts maybe of the ordinary or any desired construction and are too well known tonecessitate any further description.

In this drawing, I have for convenience shown the attachment only at oneend oi the loom, but it will be understood that there is an' attachmentat each end by which the lease rods are supported but as they arepractically duplicates of eachother, the illustration and descriptionvoi one end of the loom only is thought to be amply sulicient. Eachr ofthe attachments comprises a bracket or standard 8 which has a forked orslotted frame of the loom. The upper end of this standard is hollow toprovide va socket within which is located the shank 9 of a member l0.The shank 9 is of smaller diameter than the bore of the socket and isencircledy by a spring l1 which bears against the enlarged upper portionof the member I0 and tends to hold it elevated for a certain distanceabove the bracket. A cross or rocking member 13 has a slotted portion I4pivotally mounted upon the head l2 of the member 10 by means of a pivotpin, the amount of the rocking motion being limited by stops orprojections I5. This cross member I3 supports at one side a slide l5which carries one of the lease rods I6, as shown. The slide I5 mayconveniently have a tongue and groove engagement with the member I3 andits movement may be limited by a set screw I6 passing through a slot inthe slide and engaging the member I3. Upon the opposite side oi thepivot, the member I3 carries a vertical lug 13L through an opening inwhich passes a rod 17 to which is secured a block 18 which carries theend of the other lease rod I9. The rod 17 is encircled by a helicalspring 20 which bears at one end against the lugl and at the other endagainst the slide l5 and tends to keep the slide 15 and block I8 whichis, oi course, connected rigidly thereto through rod I7, pressedconstantly towards the left or in the direction opposite to the feed ofthe IWarp threads.

I may conveniently secure tothe under side of the block 18 at one end ofthe loom an arm 2l to which is connected a notched slide bar 22 whichpasses through a guide 23 on the frame ofthe loom and has its end no1'-mally supporting a drop bar 24, as shown in Fig. l, the bar 22 being soarranged that if moved to the right its notched portion 22 will allow itto descend and lower the drop bar 24 to engage the stop motion mechanismindicated aty 7 From the foregoing description it is thought theoperation oi my improved attachment will be obvious, but may be brieflystated as follows: The movement oi the Warp threads under the action othe harness will cause the member 13 which supports the lease rods tohave a vertical movement imparted thereto. Thus ever, any oi the threadsor yarns of the Warp be so4 firmly stuck together or entangled as toprevent their automatic separation without breaking, the slide 15 andthe lease rods will be moved to the right against the tension of thespring 20, thereby moving the bar 22 to the right until its notchedportion drops down and lowers the drop bar 24 and operates the stopmotion mechanism to arrest the loom. l

I may it desired provide the attachment Which supports the lease rods atthe opposite end with an indicator, Which, Whether or not the stopmotion connections are used, or it used fail to Work, Will show to theattendant that the threads are entangled beyond automatic separation.Such a device is shown in Fig. 4 and comprises an arm 25 pivoted to themember 13 and designed to normally drop down out oi indicatngiposition,being held in such position by gravity. The arm has an indicator head ordisk 26 of any suitable shape, and an extension 27 designed to restagainst the face of member IS. When this member is moved suddenly by theentangled Warp threads its contact with the extension Will throw the armup into signaling position.

The extension is made of spring material so as to ride over the face anddrop behind the lower edge of the member I3, holding the indicatorelevated.

Having described my invention, what I claim is:

l. In combination in a loom, lease rod carrying members supported on theloom frame and lease rods carried by said members said lease rods beingrhorizontally movable with relation to said members with the movement ofthe warp threads.

2. In combination in a loom, lease rod carrying members supported on theloom frame and havingvertical movement thereon, and lease rods carriedbysaid members and having horizontal movement thereon caused by the warpthreads.

3. In combination in a loom, lease rod carrying members supported on theloom frame and having vertical spring movement thereon, and lease rodscarried by said members, having horizontal spring controlled movement onsaid members.

4. In combination in a loom, lease rod carrying members supported on theframe of the loom and havingl vertical spring controlled movementthereon and a lease rod supported upon said members, having horizontalmovement on said members.

5. In combination in a loom, a lease rod, and lease rod carrying memberssupported npon the loom trame havingl vertical spring movement on saidtrame and springs arranged to control the horizontal movement of thelease rod.

G. In combination in a loom, lease rod carrying.,`- members havingvertical spring movement on their supports, and having also rockingmovement in vertical planes, and lease rods carried on said membershaving spring controlled horizontal movement on said members.

'i'. In combination in a loom, lease rod carrying members, horizontallymovable lease rods carried on said members, springs normally pressingsaid lease rods in a direction opposite to that of the feed of the warpthreads. stop mechanism for the loom and means connected with the leaserods for controlling the stop motion, substantially as deA scribed.

S. A lease rod carrying attachments for looms, comprising members whichdirectly support the lease rods, or rod, said member being adapted tomove vertically on said supports upon interposed springs, means forpermitting horizontal movement of the lease rod upon said supports andsprings for normally pressing the lease rod in a direction opposite thatof the feed ot the warp threads, substantially as described.

9. In combination in a loom a lease rod carrying member composed of twoparts, one movable on the other and directly carrying the lease rod orrods, a spring arranged to control the movable part a stop lnotionmechanism for the loom, and an arm connected to the movable partarranged with mechanism to engage the stop motion mechanism by movementof said movable part.

In testimony whereof, I ailix my signature in presence of two witnesses.
